To all whom it may concern: I I

Be it known that I, CHARLES KAUTMANN, a citizen of the United'States,and'a resident of Santa Ana, in the county of Orange and State ofCalifornia, have invented a new and useful Improvement in- Primers, of

which the following is a specification.

My invention is an improvement in primers, and has for its object toprovide mechanismof the character specified, for use in connection withexplosion engines using distillate gasolene, alcohol or the like, andarranged between the carbureter'and the engine, for assisting theevaporation of the fuel when starting the engine, and

wherein other mechanism is provided for permitting the use of a fuel evaorationxat' a lower temperature than theo inary fuel, for starting theengine.sh th In the drawing is own e prim' m'echanism in connection withthe mani of an engine.

In-the present embodimentofthe invention, a pipe 1 is provided,leading'from'the" jacket which encircles or incloses the exhaust pipe ofthe engine, andthe saidpipe leads to the carburetor, which may be of anydesired make. From the carbureter, the said pipe extends as shownat'fi'to the manifold of the engine, communicating therewith by means ofbranch'pipes 8 and-9', connected to the manifold as indicated at 10.

The carbureter 3 is provided with a'lateral.

nipple 11, tov which is connecteda pipe 12, having at its outerend'anelbow or depending portion13 which extends near the bottom of areceptacle 14, for containing gasolene or the like for a purpose tobe-presently described.

A T 15 is interposed in the pipe 12 near the center thereof, anda pipe16 is connected with the lateral branch. of the T'. The said pipe 16extends upwardl to the junction of the branches Sand 9 wit the body 6 ofthe manifold at which point'an elbow 17 is provided for connecting theupper end of the pipe 16 with the manifold.

A check valve 18 is arranged in the elbow 17, the said valvebeing in thepresent instance a ball valve, and arranged to permit free passage from,the pipe 16 to the manifold and to prevent the return ssage.

Valve casings 19 and 20 are interposed-in the length of the pipe 12-,the casing19- being between the carburetor and the T 15,

while the casing 20 is between the T 15 and the receptacle or reservoir14.

The valve in the casing 19 cont-rolsthe communication between thecarbureter and" the manifold, while the valve in the casing- 20 controlsthe communication between the receptacle or reservoir 14 and themanifold.

The valve 21 in the casing 19 is provided with-a radial arm 22, and alink 23 is connected at one end to the arm. The other end of the linkextends through the-radiator or to a point adjacent to the driver, and acoil spring 24 is arranged between the arm 22and a pin 25 on the outlet11.

The spring 24 acts normally to hold the arm 22 at right angles to thepipe 12, and against a stop pin 26 on the valve casing. When the arm 22is in such position, the valve is closed, closing the communicationbetween the carburetor and the manifold through-the pipes 12 and 16. Thevalve-217 in the casing 20 is provided with a radial arm 28, and a link29 is connected at one end with the free end of the arm. The other endof the link extends through the radiator or in the same manner as thelink'23'to a point adjacent to the driver to permitithe driver tooperate either valve from the seat or from in front of car. A coilspring 30 is. arranged between the arm 28, and a in 31.0n the T 15, andthe/said spring h ds the arm normally at right angles to the-pipe 12 andin contact with-a stop pin 31 on the valve casing. When the arm is insuch position, the valve is closed, and the communication between thereservoir 14 and the manifold is also closed. Both valves are The fuelstands in the carbureterat the level of the dotted line '35, andit'willbe noted that the said level is just above-the outlet 11, to which thepipe 12 is connected;- In engines of the character specifieth which usedistillate or heavier, fuel than gasolene as a fuel, it is necessary toprime theen fue with g'asolene, before'it can bestarted. is-

is due to the fact that the heavier fuel evaporates at a highertrmperature than the gasolene. \Vith the present invention however, theengine may be primed with the ordinary fuel, that is, with distillateexcept in very cold weather, when gasolene is used.

The operation is as follows: The throttle valve 32 is first closed, andthe valve 21 is opened by means of the link 23, and held open while theengine is turned over once or twice. The pipe 1 being closed, thesuction caused by the turning over of the engine draws a stream of fuelfrom the carbureter through the pipes 12 and 16 to the manifold, andfrom thence to the engine. Thevalve 21 is then released, and the spring24 closes the same. The throttle valve 732 is now opened and the engineis cranked, in

the usual manner. TVhen the sparking mechanism operates, the charge offuel drawn into the engine is ignited, and the engine starts in theusual manner, drawing its fuel from the carbureter.

In very cold weather, the procedure is somewhat different. The throttlevalve 32 is closed, and the valve 27 is opened by means of the link 29and held open while the engine is turned over once. A stream of gasoleneis thus drawn into the manifold from the reservoir 14, by way of thepipes 13 and 1G. The valve 27 is now released, and the spring 30closesthe same. The throttle valve 32 is then opened and the engine iscranked in the usual manner.

The improvement may be applied to existing engines without anyparticular change. The portion of the carbureter shown is the fuelchamber, and the pipe 12 is connected to the said chamber below thelevel of the said fuel. The elbow 17 is connected with the manifold, andno other changes in the engine proper or its connections are necessary.
